WEBINAR – FMEA - Design and Process quality
Webinar presentation
• Content– Presenting the FMEA concept and analysis process– Presenting the differences between PFMEA and DFMEA– Brief presentation of Aras Innovator and its Interface– Work in a DFMEA and collaborative management demonstration– Questions
• Organization– Duration– To ask questions
FMEA
FMEA – what is it?
Failure mode and effects analysis
http://en.wikipedia.org/wiki/Failure_mode_and_effects_analysis
FMEA- Methodology
List all usages, functions,
requirements, process steps.
Which failure can happen?
What are the effects?
How to detect or prevent these
failure?
How much it impacts the product normal
behavior?
How often it can appear?
How good these methods are to
detect or prevent such failure?
What are the improvements we can make to lower
the risk?
What are the causes?

FMEA Key Management AspectsPart/Process Integration
•FMEA is about part and process. Changes on these items can impact the FMEA.
Centralized hosting•All the FMEA in one organization should have the same format and be hosted in the same place to facilitate analytics and reports
Standardized entries•To get a real value out of your FMEA reports you need to be able to have standardized entries. Two similar causes have to have the exact same name.
Fill Collaboratively•Creating an FMEA is a lot of work and people specialist on each area should write their section of the FMEA.
Send Actions•An FMEA’s target is to lower risk by running preventive or corrective actions based on a risk analysis. Actions are run by multiple peoples, you can’t just send emails.
Consume actions’ outputs•Once the action are run. The output should be a change of the risk values. These should be easily updated in the FMEA.
